Determining habitat quality for species that demonstrate dynamic habitat selection
Determining habitat quality for wildlife populations requires relating a species' habitat to its survival and reproduction. Within a season, species occurrence and density can be disconnected from measures of habitat quality when resources are highly seasonal, unpredictable over time, and patchy. Here we establish an explicit link among dynamic selection of changing resources, spatio-temporal s...
متن کاملHabitat Selection: Demography and Individual Decisions
Arlt, D. 2007. Habitat selection: Demography and Individual Decisions. Doctor’s dissertation. ISSN 1652-6880, ISBN 978-91-576-7316-9 Habitat selection is the behavioural process determining the distribution of individuals among habitats varying in quality, thus affecting individual fitness and population growth. Models of population dynamics often assume that individuals have perfect knowledge ...
متن کاملInferring habitat quality and habitat selection using static site occupancy models
When evaluating the ecological value of land use within a landscape, investigators typically rely on measures of habitat selection and habitat quality. Traditional measures of habitat selection and habitat quality require data from resource intensive study designs (e.g., telemetry, mark–recapture, or multi–season point counts). Often, managers must evaluate ecological value despite only having ...
متن کاملSeasonal Moose Habitat Selection
The moose is Minnesota’s largest wild animal. In December 2012 moose were proposed as a species of special concern under Minnesota law due to their population decline (Baker, 2012). Time series analysis of the northeast Minnesota moose population estimates conducted by Lenarz (2012) found a significant decline between 2005 and 2012. Moose habitat lacks highly specific requirements, depending mo...
متن کاملHabitat selection in whiting
Given a choice of habitats in a laboratory experiment, whiting Merlangius merlangus preferentially spent most time over sand, then gravel and least time over a habitat with emergent structures. The introduction of a predator stimulus increased the preference for the sand habitat for large whiting, whereas small whiting had an increased preference for the habitat with emergent structures. # 2004...
